CENTRIFUGAL LIQUID-SEPARATOR.

'SPECIFICATION forming part of Letters Patent No. 362,449, dated May 3, 188'?.

Application inea Maren 1o, issu.

To all whom it may concern:

Be it known that I, CHARLES W. A. Kon-i.- KEBECK, of Camden, in the county of Camden and State of New Jersey, have invented a 5 new and useful Improvementin Centrifugal LiquidSeparators, of which the following is a specification.

This invention relates to an improvement in that class of centrifugal separators which are Io employed for separating compound liquids into their constituent liquids of different specitc gravities-for instance, for separating full milk into cream and skimmilk.

The object of 'thisV invention is to improve I5 the devices whereby the flow of the liquids through and from the centrifugal separator is controlled; and my invention consists to that end ofthe improvements, which will be hereinafter fully set forth, and pointed out in the 2o claims.

In the accompanying drawings, Figure l is asectional elevation of the separatingdrum of a centrifugal separator provided wit-h my improvements. Fig. 2 is a longitudinal section in line :c x, Fig. l. Fig. 3 is a sectional elevation of the lower portion of the drum and one of the cream-conduits on an enlarged scale. Fig. lis'aperspective view of one of the cream conduits and blades. Fig. 5 isa sectional elevation showing a modified construction of the device whereby the cream-conduit is secured to the drum. Fig. 6 is a fragmentary horizontal section of the drum, showing a modified arrangement-of the blade and cream-dis- 3 5 charge.

Like letters of reference refer to like in the several figures.

A represents the separating-drum, composed of a tight bottom, a, and imperforate peripheral Walla', and an inwardlyprojecting top ange, a2.

B represents the spindle, to which the drum is secured in any suitable manner. As shown in the drawings, the bottom ais provided with an upwardly-projecting central hub, c, which is secured to the spindle B.

d is the feed-pipe, through which the full milk is fed upon the bottom a, near the hub o. D is an annular cup or ring, which rests upon parts Serial No. 194,704. (No model.)

the bottoni a and surrounds the hub o. The feed-pipe d discharges the full milk into the cup D, and the latter is provided with horizontal discharge-pipes c, which carry the milk to the outer` wall of the drum and prevent it from disturbing the ring or annular .layer ot" cream which collects o n the inner surface of the ring of milk in the drum.

AF represents the vertical blades, which are secured in the drum, and which 'compel the liquid to rotate with the same. 6o

f represents notches or openings formed in the blades F adjacent to the outer wall of the drum for the purpose of permitting the milk to distribute itself over the inner surface of the wall of the drum.

G represents the annular trough, which is formed at the inner edge of the top flange, a2, and which receives the skim-milk from the outer portion of the drum through pipes g.

7L represents the skimming pipe, which receives the skim milk from the annular trough G.

I represents upright cream-conduits, which may be arranged at the inner edges ofthe blades F, and cast in one piece therewith. The upper portions of these conduits are made trough-shaped and open toward the axis of the drum,while the lower portions ofsaid conduits are tubular and form nozzles t', which project downwardly through openings j, formed in the bottom a of the drum. The nozzles 'i are screw-threaded externally, and are secured to the bottom of the drum by countcrsunk screwnuts It. Washers Z, of rubber or othersuitable material, are preferably arranged between the nuts 7c and the lower side of the bottom a, in the recesses of the bottom a, in which the nuts are arranged. The nozzles t are provided with collars m, which bear against the upper side of the bottom a, so that by tightening the nuts 7c the conduits I and the blades F are firmly secured to the bottom of the drum,when the blades are secured to the cream conduits.

'a represents notches formed in the upper ends of the conduits I, for admitting the cream to the same, the sidewalls of the trough-shaped conduits projecting inwardly beyond the inner surface of the ring of cream, so that the cream is taken from the upper portion of the drum, where the separation of the cream from the skim-milk is most complete.

The blades F are held in position at their upper outer corners by entering a slot in the head of screws o, which are secured to the drum, and whereby the blades are held against lateral displacement. The blades are held at their upper inner corners between lips o, formed on the underside of the annular trough G. These supports, in connection with the fastening at the lower end of the cream-conduit, serve to secure each blade irml y in place. If desired, however, the blades maybe provided with lugs or ears, whereby they are secured to the peripheral wall of the drum.

The cream-eonduitsI may be made separate from the blades F, and may besecured thereto by soldering or brazing; or the creain-conduits may be detached from the blades and be placed in different parts of the drum-t`or instance, a quarter-turn removed from the blades, as represented in Fig. G. In the lattercase the blades are secured to the drum and the skinrmilk trough G in any usual manner.

If desired, the cream-conduits may be secured to the bottom of the drum by a yieldingjoint, as represented in Fig. 5. In this case the nozzle of the conduit, which passes through the opening j in the bottom, is smallel` in diameter than said opening, and the nozzle is clamped in place by a packing-ring, r, which is forced against the nozzle by a nut or gland,

1". The latter is screwed into the lower enlarged portion of the opening j.

The full mill: entering the cup D from the feed-pipe d passes through the pipes c toward the peripheral wall ofthe drum, and then rises along said wall and is separated bythe centrifugal force into cream and skim-milk. rlhe latter passes through the pipes g into the annular trough G, from which it is removed by the skimmingpipe h. rlhe separated. cream enters the upper end of the cream-conduit I through the notch n, descends in the conduit, and escapes from the lower end thereoi into a receiving-trough, I. The lower tubular portion of the cream-conduit conducts the separated cream through the body of milk and cream on the bottom ofthe drum, which body is in the incipient stage of separation and must not comein contact with the separated cream.

Upon releasing the screw-nuts k the blades I can be removed from the drum, and the latter and the blades and their cream-conduits be thoroughly cleaned. The cup D rests loosely against an annular shoulder, q, on the bottom of the drum, and can also be readily removed and cleaned when required.

The cream descends in the conduits I by gravity, andis therefore not frothy like cream which is removed from the drum by skimming or by being thrown out by centrifugal force. The drain composed of the bottom a, peripheral wall a', top flange, a2, and annular trough G- is readily cast complete in one piece, whereby thc cost of production is greatly reduced.

The operation of the parts has been described with reference to creaming milk.

It the machine is used i'or separating a different liquid,the skim-milk discharge removes the heavy separated liquid, and the creamdischarge removes Ithe light separated liquid in the manner described.

I claim as my inventionl. rlhe combination, willi the separatingdrum having an opening in its bottom, ol' a vertical blade secured in the drum, and an npright trough secured along the inner edge of the blade, opening inwardly and terminating at its lower end in a nozzle, which is secured in the opening in the bottom of lhc drum, sub stantially as set forth.

2. The combination, willi the separatingdrinn having au opening in its bottom, of a descending cond uit, I, terminating at its lower end in a nozzle, and a screw-nut, whereby said conduit is secured in the bollom of t-he drum, substantially as set forth.

3. rlhe combination, with the drum having ils bottom provided willi an annular shoulder, (j, oi' a removable annular cup, l), resting loosely on the bottom ol' the drum and against said shoulder, substantially as sct I'orth.

\Vituess my hand this 3d day of March, 1856.
